WINDER FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 441,000, dated.November 18,1890.

Application filed December 20, 1889. Serial No. 334,367. (No model.)

To all whom it may concern:

Be it known that I, ERNST GESSNER, of Aue, Saxony, Germany, haveinvented a new and useful Improvement in WVinders for Spinning-Spindles, of which the following is a specification.

My invention relates to improvements in winders for spinning-spindles incontinuous spinning-machines, and has reference especially to theinvention presented in my patent,No. 409,957, dated August 27, 1889,upon which it is an improvement. The winders referred to in the saidpatent are composed of athread-guide, an intermediate arm, and aguiding-piece embracing the spindle and being in frictional contact withthe same.

My present invention has for its object an improved form of theguiding-piece of such winders, so as to make the winder of as littleweight as possible for the purpose of making it capable of or adapted torunning at high speed.

In the accompanying drawings, Figure 1 shows a winder applied to therail and spindle. Fig. 2 shows a view of the winder in perspective.Figs. 3 to 5 are views similar to Fig. 1, showing various modificationsof winders. Figs. 6 and 7 show in vertical section and plan views adevice employed for holding the winder in its position while beinglifted ofi from the spindle when the caps are to be doffed. Figs. 8, 9,and 10 are views similar to Figs. 1, 3, and 4, except that the winder isbelow the cap; and Figs. 11 and 12 show modified forms of the winderapplied to the spindle and rail.

Fig. 1 shows the winder composed of the thread-guide L, arm L andguidingpiece L all being preferably made of one piece of sheet metal ofas little weight as possible. The said guiding-piece consists of anoblong plate (see Fig. 2) with an opening, through which the spindlepasses, and having its plane offset or crooked near its middle, so as tobe held with its one half on the upper side of the plate A while theother half is sliding beneath. The plate A is fixed to the copping railW. The opening in the guiding-piece is somewhat longer than the diameterof the spindle, and thus permits the winder to assume an inclinedposition to the axis of the spindle.

While the winder is at rest the two parts of the guiding-piece bear,respectively, on the upper and lower face of the plate A. By a one-sidedstrain, however, caused by the tension of the thread, the thread-guide Lis drawn toward the spindle, and consequently the guiding-piece tiltssomewhat, so that its two halves come out of contact with the upper andlower face of the plate A, while at the same time friction is producedbetween the guiding-piece and the revolving spindle, so that the winderis taken along not only by the thread, but also by friction from thespindle, whereby the tension of the thread is slackened to a certaindegree. This lack of uniformity in the tension of thread arising duringspinning is automatically regulated by the new winder in the followingmanner: At the start the thread-guide is drawn toward the spindle by thetension of the thread, and consequently friction with the spindlearises, as above mentioned. With the influence of friction the threadbecomes slack, releasing the thread-guide and allowing it to be thrownaway from the spindle by centrifugal action,

so that the guiding-piece returns to its original position, bearing on.the upper and lower faces of the plate A. It then acts as abrake,retarding the motion of the winder, and thus causes the thread to betightened, which then draws the thread guide again toward the spindle.The same process is then repeated.

Fig. 3 shows a similar winder, the guidingpiece L having the same formas that shown in Fig. 1, besides being provided with a socket Lembracing the spindle, which socket is somewhat larger than the spindle,so as to fit it loosely, in order to permit the arm L" to move to andfrom the spindle. For certain purposes the parts of the guidingpiece Lwhich slide on the upper and lower faces of the plate A are lined withsome rough stuff, such as leather, felt, or other material, as shownat-X in Fig. 4. This serves to act as a brake and increase the eifect ofretard= ing the motion of the winder. I

Fig. 5 shows a winder the guiding-piece L of which embraces the spindlebelow the cap and is held in the copping-rail W in a simi lar manner tothat shown in Fig. 1. A ring R is employed to prevent the arm L from be=ing thrown away too far from the spindle by centrifugal action. When thecops are full and are ready to be dotted, the copping-rail W, with thewinders shown in Figs. 1, 3, and 4, must be lifted off from thespindles.

In order to insure that the winders will remain in their position on thecopping-rail while being lifted off from the spindle, a device isnecessary to be employed, as shown in Figs. 6 and 7. W is thecopping-rail, having fastened to it the plate A, upon which the guidingpiece L of the winder is held, sliding on the upper and lower faces ofthe said plate, as described. The rail U is attached to the copping-railWV by hinge O, and a yielding plate 0 projects from the rail and has aslot for the spindle to pass through. The sliding frameor rest M,carrying the coppingrail W, slides on a vertical rod or standard R, andhas connected to it a lever-arm H, held on pivot Y, through whichlevenarm there passes the set screw X, resting on the rail U. A spiralspring 1) is interposed between the two plates A and 0, so as to holdthe plate 0 elevated, in order to admit of a free movement of thewinder; A weight G, sliding on the vertical rod R, rests on a stud P.When the copping-rail W", with the winders, is lifted off above thespindles for the purpose of doffing the full cops, the end of thelever-arm II strikes against the under side of weight G, pushing thesame in an upward direction, whereby it is slid upon the rod R. Owing tothe action of the said weight, the set-screw X is pressed down on therail U, the spiral spring D being compressed and the plate 0 bearing onthe guiding-piece L of the winder, pressing it down onto the plateA,'which is thus held in its position. In lowering the coppingrail theweight G will come in contact with and rest upon the stud P, so that thelever-arm II and consequently spiral spring D and plate 0 are releasedfrom pressure and the guiding-piece of the winder set free.

In Figs. 8, 9, and 10 I show, respectively, the same arrangement ofparts as in Figs. 1, 3, and 4:, except that the winder is supported froma point below the cop.

In Fig. 11 the winder, instead of being stamped from sheet metal andhaving its plane crooked or offset, as in Fig. 2, is formed of two ormore wraps or convolutions of wire where it surrounds the spindle, oneend of which lies in one plane beneath plate A, and

the other portion of which lies in another plane above the plate.

Fig. 12 shows a construction and arrangement of winder similar to Fig.11, except that where the wire bears against the top and bottom of plateA it is provided with pads 00.

With reference to the application of my new device illustrated in Figs.8 to 12, I would state that I do not in this case make any claim to thebroad method of winding shown in said figures independent ofconstruction, (viz., winding the thread upon the spindle by a Winderheld in the copping-rail and in frictional contact with the spindlebelow the cop and gradually lowering said winder in addition to itstraversing motion, whereby the cop is built from the topdownward,) asthis broad method is claimed by me in a separate application', SerialNo. 334,368.

Having thus described my inventiomwhat I claim as new is 1. Thecombination, with the spindle and the rail having plate A, of a winderconsisting of a thread-guide, arm, and guiding-piece, the saidguiding-piece having an opening to receive the spindle and formed withbearingsurfaces in diif erent planes, one adapted to bear against thebottom and the other against the top of plate A, substantially as andfor the purpose described. I

2. The combination, with a spindle and the rail having plate A, of awinder composed of a thread-guide L, intermediate part L, and perforatedguiding-piece L having its plane crooked or offset and being infrictional contact with the spindle and held on the coppingrail, asdescribed, so as to bear with one half of the said guiding-piece on theupper part of the copping-rail plate while the other half slidesbeneath, substantially as and for the purpose described.

3. The combination, with the spindle and the winder, of the slidingframe M, carrying copping-rail W, jointed lever H, and hinged rail U,provided with plate 0 and spring D, set-screw X, stem R, rest P, andweight G, sliding on said stem and adapted to be struck by the lever H,substantially as and forthe purpose described.
